WELL-PUMPING POWER.

SPECIFICATION forming part of Letters Patent No. 587,525, dated August3, 1897.

Application filed June 5, 1896. Serial No. 594,388. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. GRIMES, of Bluffton, in the county ofWells and State of Indiana, have invented new and useful Improvements inl'Vell Pumping Powers, of which the following is a full, clear, andexact description.

This invention relates particularly to devices designed to be placed ata central station to operate a series of surrounding pumps for-oil orwater wells; and a main object of this invention is to provide a powerof very large capacity whereby a greater number of wells may be operatedthan has heretofore been accomplished from one power.

I will describe a well-pumping power embodyingmy invention, and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a partial elevation and partial section of a pumping-powerembodying my invention. Fig. 2 is a plan view of one form of rod-plateand crank employed. Fig. 3 is a plan view showing another form ofrod-plate and crank employed. Fig. 4 is a plan view showing stillanother form of rod-plate and crank employed. Fig. 5 is a plan view ofthe crank shown in Fig. 2. Fig. 6 is a plan view of the crank shown inFig. 3. Fig. 7 is a plan view of the crank shown in Fig. 4. Fig. 8 is aplan view of an eccentric or crank and rodplate. Fig. 9 is a plan Viewshowing another form of eccentric or crank and rod-plate. Fig. 10 is aplan view of still another form of eccentric or crank and rod-plateemployed. Fig. 11 shows still another form of eccentric or crank androd-plate. Fig. 12 is a plan view of the eccentric or crank shown inFig. 10, and Fig. 13 is a plan view of the eccentric or crank shown inFig. 11.

The power comprises a metal frame 1, supported on a base-sill 2 andconsisting of upright members 3 and horizontal members 4 and 5. Thisframe maybe made integral, or it may be made in parts'bolted together. A

master-shaft 6 extends through a boxing 7, secured to the frame portion4, and through a boxing S, secured to the frame portion 5,

and which has a step-bearing in a block 9,

bolted to the sill 2. Antifriction rollers or balls 10 will preferablybe employed in the step-bearing. Mounted on the master-shaft 6, justabove the step-bearing 9, is a mastergear 11, meshing with a pinion 12,mounted on a shaft 13, having a bearing at one end in a pillow-block14., secured to the sill 2, and also having a bearing in a boxing 15,secured to a vertical member of the frame, and on the outer end of theshaft 13 is attached a powerwheel 16.

Secured to the upper side of the mastergear 11 and arrangedeccentrically to the master-shaft 6 is an eccentric ring 17, having anoutwardly-extended annular base-flange, and loosely mounted on this ringand supported on said flange is a pump-rod-actuating ring 18, providedwith a row of annular perforations through which bolts may pass tosecure the rod-clips thereto.

Above the frame portion 5 and rigidly mounted on the master-shaft 6 is agear-wheel 19, meshing with a gear-wheel 20 on an auxiliary shaft 21 andalso meshing with a gearwheel 22 on an auxiliary shaft 23. Theseauxiliary shafts have bearings at their upper ends in boxes 24, securedto the frame member 4, and at their lower ends have step-bearings inboxes 25, secured to the frame portion 5.

Above the gear-wheel l9 and secured to the shaft 6 is an eccentric orcrank wheel 26, and

on this eccentric or crank wheel pump-rodactuating plates 27 and 28 aresecured. These plates 27 and 28 engage, respectively, with the upper andlower sides of the eccentric-wheel and also engage the periphery of saideccentric-wheel. These plates 27 and 28 are securely bolted together,and their outwardlyextended flanges are provided with perforationsthrough which fastening-bolts may pass to secure a pump-rod clip-plate.

Above the eccentric mechanism just described and secured to the shaft 6is an cecentric or crank wheel 29 similar in construction to theeccentric-wheel 26. The pumprod-actuating plates 30 and 31, however, forthis eccentric-wheel have inwardly-extended 'flanges at their innercircumference, which engage against the inner side of the lateralflanges on the wheel.

On the upper end of the shaft 6 is secured a crank-arm 32. On this crank32 is a disk formation 33, which is engaged at the upper and lower sidesand on the periphery by pumprod-actuating plates 34 and 35, boltedtogether in a manner similar to that of the plates 27 and 28.

On the auxiliary shaft 21 above the gear 20 is an eccentric or crankwheel 36,having an annular channel formed in its periphery, within whichpump-rod-actuating rings or plates 37 38 engage. The eccentric 36 ismade in two sections, as plainly indicated in Fig. 11, a division beingmade transversely through the hub of the eccentric, and the sections aresuitably bolted together. The plates or rings 37 and 38 are also eachmade in two sections,

the adjacent ends of the twosections of a ring On the upper end of theshaft 21 issecured a crank-arm 39, having at its outer end an annularflange portion 40, upon which is mounted a rod-actuating ring or plate41. This ring or plate 41 is held from upward movement relatively totheflange by means of a ring 42, bolted to said flange and engaging overthe top of the ring or plate.

Mounted on the shaft 23- above the gearwheel 22 is an eccentric or crankwheel 43, around which engage the rod-actuating rings or plates 44 45.These rings or plates 44 45 engage the periphery of said wheel, and alsohave inwardly-extended flange portions to engage the upper and lowersides of said wheel. This wheel 43 is made in sections similar to thoseof the Wheel 36, and the plates 44 45 are also made in sections similarto the rings or plates 37 38, and these rings or plates 44 45' aresecurely bolted together. On the upper end of the shaft 23 is acrank-arm 46, having an annular flange portion 47, upon which is mounteda pumprod-actuating ring or plate 48. This ring or plate 48 has aninwardly-extended flange extending over the top of the annular flange,and as this ring or plate is loosely mounted on the bearing it may beremoved upwardly therefrom.

Owing to the enormous load to be handled in {pumping oil and water wellsthere is a certain amount of vibration in the rods or line that becomescentralized at the power and has a tendency to jar loose the splines,keys, or set-screws, as ordinarily employed for securing the actuatingdevices to shafts.

Thus the gearing and pump-rod-actuating sition. To overcome thisdifficulty, I have successfully put into use the principle of at.-',taching the gearings, the eccentrics, and

cranks to their respective shafts with a feather or key placedlongitudinally on the shaft and engaging in a groove in the hub, asindicated at 49 in Fig. 13, and then placing transversely through anotch in the shaft and through the hub a key 50, the said key 50 beingof a greater width than thickness. By

this construction it will be seen that the actuating mechanism is firmlyattached to the shaft, so as to rotate with the shaft and also so as toprevent a vertical movement of the actuating devices relatively to-theshaft. Having thus described my invention, I claim as new and desiretosecure by Letters Patent- 1. A well-pumping power, comprising a frame,a master-shaft supported vertically therein, auxiliary shafts supportedby said frame and having gear connection with the master-shaft,pump-rod-actuating deviceson the master-shaft, pump-rod-actuatingdeviceson the auxiliary'shafts, and driving mechanism having connection withthe master-shaft, substantially as specified.

2. A well-pumping power, comprising upright members and transversemembers, a master-shaft extended through boxes secured to saidtransverse members and having a step-bearin g provided withantifriction-rollers, auxiliary shafts having bearings through boxes onthe upper transversemember of the frame and step-bearings in boxes onthe lower transverse member of the frame,

gear-wheels on said auxiliary shafts engaging with a gear-wheel on themaster-shaft, crank-arms on each of said shafts above the uppertransverse member of the-frame,-pumprod-actuating rings or plates onsaid cranks, a master-gear on the lower portion of the master-shaft, anda driving-pinion engaged therewith, substantially as specified.

3. In a pumping-power for wells, the combination with a rotary shaft, ofan eccentric or crank thereon consisting of two sections boltedtogether, the division being made transversely through the hub andtransversely through the rim in a line between the hub and the center ofthe rim, and pump line or rod plates mounted on the eccentric or crank,each plate consisting of two sections bolted together at the ends, thejoints of one plate being at right angles to the joints of the otherplate, the said plates having a 'number of holes for lineor rodfastening bolts, substantially as specified.
